Assignment 3 
Due Wednesday 4/05/06

1)	a) Draw a figure that admits a bilateral reflection (e.g. a vertical 	reflection).
	b) Draw a figure that admits a horizontal reflection. 	
	

2) 	a) Draw a figure which admits two reflections
	b) Redraw your figure in a) and color it so that you “lose”one of the reflections. 	

3) Construct a triangle whose three sides are 30, 60, and 90 degrees.   
 Be sure to do it one step at a time, so that it is clear what the order of your construction is.  
Color pencils might help.  Give a short discussion of why your triangle has angles of  30, 60, and 90 degrees.
